DETAILED DESCRIPTION

Various detailed embodiments of the present disclosure, taken in conjunction with the accompanying figures, are disclosed herein; however, it is to be understood that the disclosed embodiments are merely illustrative. In addition, each of the examples given in connection with the various embodiments of the present disclosure is intended to be illustrative, and not restrictive.

Throughout the specification, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise. The phrases “in one embodiment” and “in some embodiments” as used herein do not necessarily refer to the same embodiment(s), though it may. Furthermore, the phrases “in another embodiment” and “in some other embodiments” as used herein do not necessarily refer to a different embodiment, although it may. Thus, as described below, various embodiments may be readily combined, without departing from the scope or spirit of the present disclosure.

As explained in more detail, below, transaction cards, systems, and methods for performing fraud detection at POS devices based on analysis of feature sets are disclosed. In one embodiment, an exemplary transaction card may comprise one or more sensors configured to collect pre-card-use sensor data regarding a user of the transaction card, circuitry configured to assemble such data into feature sets and perform fraud detection, and data storage configured to store the sensor data and/or feature sets. According to some aspects, the fraud detection may comprise: comparing user specific sensor data, collected via the transaction card for a current transaction, to a user-specific risk profile validation model, generated via the transaction card based on prior transactions, to determine a risk score for the current transaction; and transmitting the risk score to a card transacting device when a card user presents the transaction card to a card transacting device during an attempted transaction. Further, the risk score may enable the card transacting device to evaluate a risk associated with accepting the transaction card to complete the at least one transaction. In one more detailed example, the fraud detection may comprise: receiving the user-specific sensor data from the one or more sensors; utilizing the user-specific sensor data to generate a plurality of user-specific characteristics of the user; encoding the plurality of user-specific characteristics of the user with at least one cryptographic hash to generate a user-specific risk profile validation model of the user; storing the user-specific risk profile validation model of the user in the data storage; comparing the user specific sensor data collected for a current transaction to the user-specific risk profile validation model to determine a risk score for the current transaction; and transmitting the risk score to a card transacting device when the user utilizes the transaction card to attempt at least one transaction with the card transacting device. Further, in certain exemplary implementations, the data received regarding usage of the transaction card, e.g., the sensor data received from the sensors, etc., may be collected and/or stored as data objects and/or data structures (e.g., data cubes, data arrays, N-dimensional data warehouses, etc.).

According to some embodiments, the innovations herein may be implemented in connection with a financial service entity that provides, maintains, manages, or otherwise offers financial services. Such financial service entity may be a bank, credit card issuer, or any other type of financial service entity that generates, provides, manages, and/or maintains financial service accounts that entail providing a transaction card for one or more customers, the transaction card being used at a POS device in regard to such financial services. Financial service accounts may include, for example, credit card accounts, bank accounts such as checking and/or savings accounts, reward or loyalty program accounts, debit account, and/or any other type of financial service account known to those skilled in the art.

FIG. 1 depicts an exemplary system 100 for improved fraud detection associated with use of a transaction card by an individual, in accordance with one or more embodiments of the present disclosure. System 100 may include a server 101, a mobile device 160, a transaction card 110 with circuitry 113 disposed therein, and a point-of-service or point-of-sale (POS) device 195, which may all communicate 103 over a communication network 105. When a user attempts a transaction with a transaction card, the business or merchant associated with the POS device 195 and typically a financial institution, such as a credit card company that has issued the card to the user, may wish to assess whether the user using the credit card is the authorized user in order to approve the transaction. Some embodiments herein may also leverage the fact that the user of the transaction card may most likely carry or is near to the user's mobile device, such as a cellphone, tablet or smartphone, for example, and may use functionality associated with the user's mobile device and the transaction card, including interaction between the two, as a part of various fraud detection and/or authentication processes for approving a transaction and/or authorizing the user to use the transaction card to purchase goods or services.

In some embodiments, server 101 may be associated with one or more entities that are stakeholders to the attempted transaction, such as the business or merchant, one or more financial services providers, such as an issuer of a credit card, debit card, or other transaction card associated with the attempted transaction.

In some embodiments, transaction card 110 may include various circuitry 113 including circuitry capable of communicating 132 various card-related information from the transaction card 113 to the POS device 195. Such card-related information may include one or both of: (i) one or more sensory inputs associated with a use of the one or both of the card and the mobile device for the transaction, and/or (ii) an identifier (1) associated with a known owner of one or both of the card and/or the mobile device and (2) used to determine whether the one or more sensory inputs are consistent with prior transaction behavior of the owner. As used herein, the terms “sensory inputs” and “sensor data” are synonymous.

In the embodiment shown in FIG. 1, an illustrative POS device 195 may comprise: one or more processing components and/or computer readable media 170, memory 180, communication circuitry and/or interfaces 185, at least one card reading component 190, and at least one cluster of data regarding known card-usage behavior of a plurality of card holders. The card reading component(s) 190 may be configured to read information from a transaction card 110, for example, the at least one card reading component may comprise one or more of a magnetic stripe reader, a chip reader, and/or a first near field communication (NFC) component. Communication circuitry and/or interfaces 185 may comprise at least one mobile device transceiver component configured to communicate, during execution of a purchase transaction, with a mobile device 160 presented for payment, the mobile device transceiver component comprising a second NFC component.

With regard to the disclosed innovations, the processing components and/or computer readable media 170 may be configured to execute instructions associated with performing methods such as that described below in more detail in connection with FIG. 4. In certain embodiments that involve use of clusters to compare current card usage data to expected card usage data, for example, the one or more processing components and/or computer readable media 170 may be configured for: obtaining, from one or both of the transaction card 110 and/or the mobile device 160, upon initiation of the transaction: one or more sensory inputs, and/or an identifier; mapping the one or more sensory inputs to a first cluster position of at least one particular cluster of a plurality of clusters 195; determining whether the first cluster position of the at least one particular cluster mapped for the transaction corresponds to a second cluster position of the at least one expected cluster associated with the known owner of one or both of the card 110 and/or the mobile device 160; and initiating at least one second factor authentication process to establish that the individual transacting with the POS device is the known owner of one or both of the card 110 and/or the mobile device 160 being used in the transaction.

According to various embodiments, the sensory inputs may be configured to be associated with a user of the card 110 and/or the mobile device 160 involved in the attempted transaction. In some embodiments, such an identifier may be configured to be: (1) associated with a known owner of one or both of the card and/or the mobile device, and/or (2) used to determine whether the one or more sensory inputs are consistent with prior transaction behavior of the owner. In some embodiments, the sensory inputs may be combined with various information regarding the transaction card and/or the user or owner, to create a set of features (or ‘feature set’) regarding the attempted transaction.

Historical collections of such feature set data, i.e., for each owner of a transaction card 110 and/or mobile device 160, may then be assembled and processed into a set of clusters comprised of a plurality of clusters that are each associated with sets of the features that define typical card transactions regarding which each user in question commonly performs. A set of recent historical feature information for any one user will define a first cluster from among the plurality of clusters, to which that user's normal transaction features will map.

In some embodiments, the clusters are created and redistributed by the server 101, for example, by a financial service provider running the server 101. Once created and/or revised, the plurality of clusters may be provided (e.g., by download or by chip or card) to POS devices, to provide the merchants associated with the POS devices a set of clusters 195 into which all customers of the financial service providers are mapped. This allows the merchants and POS devices to determine, by comparison of data received from the transaction card against the clusters 195 locally-stored in the POS device, whether the current transaction is more or less likely to be a fraudulent transaction.

Further, according to some embodiments, the clusters 192 may be configured to define sets of features regarding prior known interactions of owners of cards with POS devices 195. According to embodiments, herein, a variety of mathematical techniques may be utilized to create the plurality of clusters from card owners' historical card-usage information. For example, the plurality of clusters may be created by one or more machine learning algorithms, by hashing the feature data, by using a point-distance function of the historical feature data, by use of vector mathematics to map the historical data into the clusters, and/or by other known clustering techniques. According to exemplary embodiments discussed herein, the prior transaction data may be configured into clusters that define sets of hashed, and/or learned features regarding prior known interactions of owners of cards with POS devices. Further, the prior known interactions may be configured to be mapped by machine learning techniques into the plurality of clusters. Here, for example, the prior known interactions may be configured to be mapped by machine learning techniques into the plurality of clusters such that learned features including prior sensory inputs for each card owner have been mapped to at least one expected cluster.

In some instances, such as when the first cluster position of the at least one particular cluster does not correspond to the second cluster position of the at least one expected cluster, the POS device (e.g., via the processing components and/or computer readable media) may be configured to provide risk assessment and/or set a risk score (and take appropriate action) as a function of how far outside the owner's predicted cluster an attempted transaction falls. Here, for example, at least one second factor authentication process may be initiated, if the mapped cluster is too far from the expected cluster, to establish that the individual transacting with the POS device 195 is the known owner of one or both of the card 110 and/or the mobile device 160 being used in the transaction.

It is noted that the disclosed POS devices, systems, platforms, methods, and computer-readable media include or involve a fraud detection mechanism that may include and/or involve a POS device 195 configured to perform various automated functionality set forth herein. Unlike existing solutions using conventional POS devices, the present innovations may utilize an improved POS device 195 that may, via obtaining the features and sensory inputs from the transaction card as well as the mapping of the sensory inputs to a cluster position of a plurality of clusters, be configured to detect fraud at the point-of-service, in the moment prior to authorizing the transaction. In these and other ways, implementations involving the present POS devices 195 and associated features, functionality, and POS fraud detection mechanisms represent improvements over existing fraud detection for card-based transactions.

The disclosed implementations for detecting fraud at point-of-service also improves utilization of both processing and communication resources. As an initial matter, the present embodiments may store and map the cluster of learned features from customers on the local POS device at the merchant site. This obviates communication bandwidth otherwise used for network access during the transaction to perform fraud detection, such as with prior systems, e.g., those that require contact with a financial institution to perform the fraud detection on the server side and transmit instructions back to the POS device to authorize the transaction. Such benefits are achieved by embodiments that include mapping one or more sensory inputs to a first cluster position, determining when the first cluster position of the at least one particular cluster mapped for the transaction matches a second cluster, and initiating at least one second factor authentication process when the first cluster position of the at least one particular cluster does not correspond to a second cluster position of the at least one expected cluster. Further, because present embodiments need only perform a straightforward mapping of the identifier and/or feature information against a local cluster, without involving any additional entities and computer systems outside/beyond the POS device, the processing and compute resources required are reduced substantially compared to existing techniques for fraud detection performed for POS device transactions. Moreover, improved POS devices having the disclosed fraud detection mechanisms improve responsiveness, efficiency, accuracy, robustness, autonomousness and fault-tolerance ability of POS fraud detection. Implementations herein also reduce likelihood of merchant exposure to fraud involving cards and/or mobile devices, as well as likelihood of “lag time” caused by communication or network intermittent availability or failures, thereby reducing or eliminating the need for communicating with remote entities at the moment of the transaction to make a fraud determination.

Turning back to FIG. 1, server 101 may include at least one processor 102 and a memory 104, such as random-access memory (RAM). In some embodiments, server 101 may be operated by the financial institution issuing the transaction card, by the merchant, and/or by any transaction clearing house used for authorizing the credit card for use.

Transaction card 110 may be formed from plastic, metal, or any other suitable material. Transaction card 110 may include card circuitry 113 formed directly therein, and/or disposed therein by gluing, bonding or by any suitable adhesion method for affixing circuitry to the material of transaction card 110. Card circuitry 113 may be configured to utilize any hardwired circuitry. Card circuitry 113 may be implemented as one or more integrated circuit chips, and/or electronic devices, electrically interconnected and bonded to one or more circuit boards, for example. Further details and embodiments of exemplary transaction cards are shown and described in connection with FIGS. 2-3, below.

Referring to the high-level block diagram of FIG. 1, card circuitry 113 may include a memory 120, at least one processor 125, sensors and circuitry 130 associated with acquiring the sensor data and information, authentication circuitry 127, communication circuitry and interface 140, and a power source 145. Memory 120 may store code, such as for the authentication circuitry 127, which when executed by processor 125 may cause processor 125 to implement assembling and transmitting data to the POS device and/or other, related schemes herein (such as pairing with mobile device 160) to perform fraud detection. As set forth in more detail, below, such features provide means to verify whether or not a user of transaction card 110 is an authorized user of the card, e.g., to approve the transaction when the user attempts to use the transaction card to purchase goods and/or services at POS device 195.

In some embodiments, transaction card 110 may include various sensors and sensor circuitry 130, which may be connected via respective electrical connections to memory 120, card processor 125, authentication circuitry 135, communication circuitry and/or communication interface 140, and/or power source 145. With regard to the disclosed innovations, the sensors and sensor circuitry 130 may be configured to collect a user-specific pre-card-use sensor data regarding a user of the transaction card 110. Here, for example, the user-specific pre-card-use sensor data may comprise one or both of: i) first sensor data regarding at least one action previously performed with the transaction card 110 by the user; and ii) second sensor data regarding at least one activity, associated with the transaction card 110, engaged into by the user. In some embodiments, the user-specific pre-card-use sensor data may be collected by the one or more sensors 130 beginning from an activation of the card 110 through completion of the current transaction.

In some embodiments, power source 145 may be used to power card circuitry 113. Power source 145 may include, for example, a battery, a solar cell, and/or any suitable energy harvesting device, capable of generating enough power for powering card circuitry 113. In other embodiments, the transaction card may be powered upon swiping or inserted the card into a slot in POS terminal 195 such that the power source may be POS terminal 195 itself or any other device into which the transaction card is swiped or inserted. The transaction card 110 may also be powered by movement, or by induction, or by other near-field electromagnetic energy derived from nearby sources, such as mobile device 160, POS device 195, or other known sources. Once powered, the transaction card may begin assembling the sensory data and/or feature set for communication to the POS terminal 195.

Mobile device 160, such as a smart phone or other portable or wearable electronic device, may include mobile device circuitry. Mobile device circuitry may include a mobile device processor, a memory, such as RAM, communication circuitry and interface, and any input and/or output device, such as a touchscreen display. RAM may store code that, when executed by processor, may cause processor to implement aspects of one or more fraud detections schemes herein, including those involving pairing with transaction card 110 to verify if a user of the transaction card 110 is an authorized user of the card. In some embodiments, any transaction card application running on mobile device 160, such as an application supplied by the financial institution issuing the transaction card and/or managing the transactions of the transaction card user, may include various modules that may transmit information to the POS device, relay information back to the financial institution (e.g., server 101), and communicate with other computing components.

Various embodiments associated with FIG. 1 and related disclosure herein solve a technical problem of ensuring that a transaction card is only used by the authorized user of the transaction card, e.g., the account owner. Various features and functionality disclosed herein may be utilized in connection with fraud detection and/or authentication processes that involve pairing of transaction card 110 with mobile device 160 when implementing multi-factor authentication (MFA) schemes, for example to authorize the card for use by the user. In other embodiments, various information related to the successful pairing of the transaction card and the mobile device may be relayed back to server 101 (e.g., server processor 102) so as to approve transactions for purchasing goods and/or services with the authorized user's transaction card.

In some embodiments, an initial authentication for pairing the transaction card with the mobile device may be implemented by the user contacting the financial institution from the user's mobile device to initially authorize the pairing of transaction card 110 with mobile device 160 so as to receive pairing approval. In other embodiments, the pairing and/or unpair processes between the transaction card and the mobile device may occur automatically and seamlessly such as without any action on the part of the user, particularly if the same mobile device had been previously paired with the same transaction card in the past. In yet other embodiments, proximity MFA may use biometrics (e.g., fingerprint, voice recognition, etc.) and/or a password entered by the user and/or a swiping of the mobile device screen by a finger of the user and/or the proximity of the transaction card to the mobile device or any client device, for example, to pair or unpair the transaction card with the client.

In some embodiments, when the transaction card may include a battery as power source 145, the transaction card and the mobile device may be configured to pair with the transaction card on the fly when the transaction card is used during a transaction, so as to conserve power stored in the battery.

In some embodiments, if the transaction card is determined to be in possession by an unauthorized individual via implementations herein, e.g. at/via POS device 195, an entity associated with the transaction, such as the merchant deploying the POS terminal 195, may generate or receive an alarm or alert that the card user is potentially unauthorized (e.g., an alert on a display of POS terminal 195) or that additional authentication, such as second-factor authentication, should be performed to verify that the transaction is not fraudulent.

FIG. 2 shows a diagram of an exemplary transaction card 110, consistent with disclosed embodiments. In some embodiments, transaction card 110 may be the approximate size and shape of a traditional credit card, debit card, or the like. Transaction card 110 may have embedded electronics for performing various aspects of the disclosed innovations. As shown, transaction card 110 may include at least one processor 210 or processing circuitry, memory 230, power source or power circuitry 240, one or more sensors 250, communication circuitry/devices 255, (optional) biometric input elements and/or circuitry 260, a magnetic stripe 280, and other coupling circuitry 220 such as an electronic chip element. Power source or power circuitry 240 may include elements that generate power for the card upon coupling to a POS device, such as by connection via an electronic chip, and/or such circuitry may include a voltage supply such as a battery. In some embodiments, transaction card 110 may include more or fewer components than shown in FIG. 2.

Processor 210 may comprise one or more known or specialized processing devices, of sufficient size and form factor to fit within transaction card 110 when configured to be about the size of a traditional credit or debit card. In some embodiments, processor 210 may include any configuration capable of performing functions related to the disclosed methods such as, for example, generating and transmitting the identifier, feature set, and/or sensory data associated with usage of the transaction card 110, which may be based on the various sensory inputs 250, 260 generated by the transaction card 110. Processor 210 may also control power source 240, send and receive data, read from and written to memory 230, receive and analyze data from sensors 250, process information or instructions associated with the coupling circuitry 220, receive and process input from the biometric input elements and/or circuitry 260, and any other functions consistent with the disclosed embodiments.

Memory 230 may include volatile or non-volatile, magnetic, semiconductor, or other type of storage elements and/or tangible (i.e., non-transitory) computer-readable medium that stores relevant data, such as information needed for or associated with conducting card transactions. With regard to the data generated by the card for mapping against the cluster stored in the POS device, such data may be stored as a set of features, which may be encrypted or otherwise secured, and/or it may be transformed, e.g., by hash, fuzzy-hash, etc., into an identifier, with the identifier being stored in memory 230 for transmission to the POS device. Data of prior features and/or identifiers may also be stored in the memory, 230, wherein a historical list of such data may be maintained and used for determining the current cluster in which the owner of the transaction card is to be assigned. In one exemplary implementation, the historical data (feature sets) regarding a card owner's prior transactions are stored in memory, and uploaded periodically to the server 101, so that the server 101 may confirm or recalculate the cluster to which the owner's expected behavior is assigned. According to embodiments herein, the memory 230 may also store user information, data needed or used by the card or the POS device to achieve the innovations herein, other computer-executable instructions and/or data known in the art.

Power source 240 may include a power storage device such as a battery or capacitor, a power receiver such as an inductive power coil or a wireless power receiver, a power generator such as a solar or kinetic power generator, or any combination thereof. In some embodiments, power source 240 may include one or more other known devices capable of generating, receiving, and/or storing electrical energy.

One or more sensors 250 may include one or more devices capable of sensing the environment around transaction card 110, movement of the transaction card 110, and/or other detectable interactions involving the transaction card 110. In some embodiments, such sensors 250 may include, for example, one or more of a camera, an optical sensor, a microphone, a gyroscope, an accelerometer, a shock sensor, a position sensor, a light sensor such as an ambient light sensor, a temperature sensor, a touch sensor, a conductivity sensor, and/or a haptic sensor.

Sensors 250 may also include one or more buttons, switches, other tactile input mechanisms, or other forms of user-derived input for receiving an indication or instruction from a card user. In some embodiments, such input devices may receive a sequence or series of inputs, to cause processor 210 to perform various functions associated with the disclosed embodiments.

Further, while shown separately at 260, sensory inputs may also be obtained via the biometric input elements and/or circuitry 260. In some embodiments, such biometric input elements and/or circuitry 260 may include, for example, one or more of a fingerprint sensor, an optical sensor that detects one or more of a card user's face, eyes, or other distinguishing features of the card user, and/or a sensor that detects electromagnetic energy emitted from the card user.

The transaction card may, optionally, also include a display, which may comprise a screen, indicator light, or other appropriate device for displaying a status or message to user. In some embodiments, display may include a small LCD screen, e-ink screen, or OLED display or one or more LEDs. In some embodiments, display may provide notifications, prompts, and/or messages to user.

In some embodiments, transaction card 110 may include communication circuitry/devices 255 such as antennae and/or NFC (near-field communication) circuitry, for transmitting and/or receiving data from one or more external locations. Communication circuitry 255 may comprise a short-range wireless transceiver, or a near-field communication chip. Communication circuitry 255 may be configured to communicate with mobile device 160, a contactless card reader associated with the POS device 195, other systems, and/or other sensors configured to detect the presence of transaction card 110.

In some embodiments, transaction card 110 may include at least one magnetic stripe 280 or other magnetic communication medium that may share or read magnetically-stored information. In some embodiments, magnetic stripe 280 may be controlled by processor 210. For example, processor 210 may write, clear, and rewrite magnetic stripe 280, to provide particular account information.

Referring to FIG. 3, a simplified block diagram showing various exemplary sensors 250 and biometric input elements and/or circuitry 260 of transaction card 110 is illustrated. In various embodiments, the sensors 250 may comprise, for example, one or more of: a camera 350A, a microphone 350B, a gyroscope 350C, a NFC antenna and/or detector 350D, one or more motion detectors 350F such as an accelerometer, pedometer and/or linear acceleration sensor, one or more switches 350F including various tactile or touch sensitive elements, an attitude sensor 350G, one or more optical, light or IR sensors 350H, and/or other sensors 350I such as a GPS-related sensor, an electronic compass, a network card to detect nearby WiFi, RF or other wireless signals, and/or other such sensors known in the art. Further, the biometric input elements and/or circuitry 260 may comprises, for example, a fingerprint sensor 360A, a face or eye recognition sensor 360B and/or other biometric sensors 360 n such as palm scanner, chemical (e.g., sweat, etc.) sensor, or other such sensors known in the art. In some embodiments, transaction card 110 may be configured to collect a set of pre-card-use data from a plurality of such sensors that characterized a card owner's customary use of the transaction card 110. In this way, the transaction card may collect sensor data defining a regular feature set or pattern associated with the known card owner, e.g., information that defines a definitive pattern associated with a known card owner, such as recurring sensor data collected each time the card owner removes the transaction card from his or her wallet.

In one exemplary implementation of transaction card 110, the card circuitry 113 (FIG. 1) may be configured to receive the user-specific sensor data from the one or more sensors 250; utilize the user-specific sensor data to generate a plurality of user-specific characteristics of the user; encode the plurality of user-specific characteristics of the user with at least one cryptographic hash to generate a user-specific risk profile validation model of the user; store the user-specific risk profile validation model of the user in the data storage 230; compare the user specific sensor data collected for a current transaction to the user-specific risk profile validation model to determine a risk score (e.g., an identifier) for the current transaction; and transmit the risk score to a card transacting device when the user utilizes the transaction card to attempt at least one transaction with the card transacting device. Here, for example, such risk score may be configured to allow the card transacting device to evaluate a risk associated with accepting the transaction card 110 to complete the attempted transaction.

Further, according to various disclosed embodiments, circuitry 113 may be also configured to compare a current instance of collected sensor data to past instances of sensor data reflected in the user-specific risk profile validation model, e.g., to perform various actions such as: (i) activating or deactivating the card 110; and/or (ii) indicating to the card transacting device that the card 110 is invalid, or that the card 110 is in possession of a potentially fraudulent user. Here, in one embodiment, the past instances of the user-specific risk profile validation may be stored in the data storage 230. In some implementations, the current instance of the user-specific risk profile information associated with a current transaction attempt may be configured to be transmitted to a separate or remote server involved with validation of card transactions. In some other implementations, the user-specific risk profile calculation of the current transaction and the user-specific profile validation models of prior transactions may be configured to be compared by the card transacting device, and/or be compared by the transaction card 110 itself, to authorize the attempted transaction.

With regard to the user-specific risk profile validation model, embodiments herein may be configured such that the transaction card 110 may generate the user-specific risk profile validation model of the authorized card users' behavior based on the user-specific characteristics of prior instances of the card sensor data recorded for authorized transactions performed using the transaction card 110. According to various embodiments, such user-specific risk profile validation model may be built utilizing a machine learning algorithm. In implementations, the building of such user-specific risk profile validation model may comprise building a cluster that represents the customary behavior of the user when initiating transactions. Here, for example, the comparing the validation score of the attempted transaction against the validation scores of the prior instances may comprise determining whether or not the validation score of the attempted transaction maps to the cluster.

Further, in various embodiments, the user-specific risk profile validation model may be configured such that one or more outlier assessment techniques are utilized in the process, e.g., to generate the user-specific risk profile validation model, and/or to compare the validation score of the attempted transaction against the mode. Such outlier assessment techniques may include a principal component analysis (PCA), a Z-score analysis, and/or other outlier detection methods including but not limited to linear regression, neural networks (RNN, CNN, DNN, etc.), DBscan, kNN, and the like. Here, it is noted that PCA is only applicable in embodiments where the output is multivariate (e.g., a vector, matrix, feature set, etc.). Examples of such PCA embodiments include embedding or mapping an input to a high dimensional space, applying a filter to an image, and the like. Further, according to some embodiments, the validation score of the attempted transaction may be based on the card sensor data for a predetermined amount of time preceding a transaction, such as the final 30 seconds of the card sensor data prior to the completion of each respective transaction. In certain embodiments, the transaction card 110 may be configured such that only the validation scores of a predetermined quantity of most-recent transactions are stored and used for calculation of the user-specific risk profile validation model. For example, only the validation scores of the 1,000, 500, or 250 most-recent authorized transactions of the prior instances might be stored in the data storage 230 for such use. In one example, if the transaction is not completed or not authorized, the validation score for the current transaction may be discarded.

In some implementations, the risk score may be encrypted for secure storage on the card 110, and/or for secure transmission from the card or elsewhere. Further, an encryption key utilized to decrypt the encrypted risk score may be stored on the card 110. According to some aspects, the user-specific risk profile validation model may be also encrypted for secure storage on the card 110.

Moreover, according to some embodiments, the transaction card 110 may further comprise a control circuit, which may be integral with the processor 210 or part of other card circuitry 113. Such control circuit may include an activation element configured to activate the card 110 responsive to one or both of: (i) an action or activity of a user of the card 110; and/or (ii) an output of the one or more sensors 250, occurring prior to current usage of the card 110 for a transaction at the card transacting device. The activation element may include and/or involve a sensor 250 such as a switch 350F, a biometric element 260, a component associated with the communication or NFC elements, or the like. In various implementations, for example, the action or activity of the user that activates the transaction card 110 may comprise one or more of: removing the card from a wallet or other receptacle in which the card is stored; activating a switch or touch-sensitive area of the card; moving the card in proximity to a mobile device known to the card; moving the card into proximity with a near field communication (NFC) device; an action or activity that supplies power to the card; an action or activity that induces electrical activity in the card; a predetermined action (e.g., flick) that activates a predetermined sensor (e.g., motion sensor); and/or one or more other actions that activate at least one sensor 250.

In various implementations, one or more of steps 404, 406, 408, and/or 410 may be performed by the circuitry of the transaction card 110. In some embodiments, the step 406 may comprise utilizing the user-specific sensor data to generate a plurality of user-specific characteristics of the user (e.g., at least 2, 2-5, 2-10, 2-20, 3-5, 3-10, 3-20, 4-5, 4-10, 4-20, etc.).

As set forth, above, illustrative process 400 may include a step of transmitting the risk score to a card transacting device when the user utilizes the transaction card to attempt at least one transaction with a card transacting device, at 414. In some implementations, the user-specific risk profile validation model of the user may be configured to allow the card transacting device to evaluate a risk associated with accepting the transaction card to complete the at least one transaction.

Here, it is noted that various transaction cards, systems, platforms, methods, and computer-readable media herein relate to fraud detection and/or risk determination mechanisms that include and/or involve a transaction card configured to perform various automated functionality with the POS device during an attempted transaction. Unlike conventional solutions, the present innovations may include and/or involve a transaction card that may, via data collected from the one or more sensors, be configured to reduce fraud and/or determine risk wholly at the POS device or wholly between the POS device and the transaction card. In these and other manners, implementations involving the transaction card empowered with the disclosed fraud detection and/or risk assessing mechanisms represent improvements over conventional fraud detection and risk determining techniques associated with existing transaction cards.

In some aspects, the innovations herein may also be implemented at a POS device upon initiation of a transaction involving: (1) a transaction card 110, or (2) the transaction card 110 and a mobile device 160 associated with an individual transacting with the POS device.

In some implementations, such fraud determination may be performed on-site at the POS device and/or otherwise without the need for communicating with remote entities to make the fraud determination. Exemplary embodiments may also include initiating at least one second factor authentication process to establish that the individual transacting with the POS device is the known owner of the card and/or the mobile device being used in the transaction. Embodiments herein may be configured to initiate such second factor authentication process when the sensor data collected for the attempted transaction does not correspond to the user-specific risk profile validation model. In some embodiments, the second factor authentication may be triggered via processing performed by the POS device, and the second factor authentication may be performed at the POS device.

Further, according to some embodiments, the second factor authentication process may comprise generating an alert to a merchant associated with the POS device. In other embodiments, the second factor authentication process may comprise generating an alert to a financial services entity associated with one or more of the POS device, the card, and/or the owner of the mobile device.

The card of claim 1 wherein the circuitry is further configured to compare a current instance of the user-specific risk profile validation model to past instances of the user-specific risk profile validation model to one or more of: (i) activate or deactivate the card; (ii) indicate to the card transacting device that the card is invalid or that the card is in possession of a potentially fraudulent user; and/or (iii) transmit a warning signal or message via physical or wireless connection.
 5. The card of claim 4 wherein the past instances of the user-specific risk profile validation are stored in the data storage.
 6. The card of claim 1 wherein a current instance of the user-specific risk profile validation model associated with a current transaction attempt is configured to be transmitting to a separate or remote server involved with validation of card transactions.
 7. The card of claim 1 wherein the user-specific risk profile validation model of the current transaction and the user-specific profile validation models of prior transactions are configured to be compared by the card transacting device and/or the transaction card to authorize the at least one transaction.
 8. The card of claim 1 wherein the transaction card generates the user-specific risk profile validation model of the authorized card users' behavior based on the user-specific characteristics of prior instances of the card sensor data recorded for authorized transactions performed using the card.
 9. The card of claim 8 wherein the user-specific risk profile validation model is built utilizing a machine learning algorithm.
 10. The card of claim 9 wherein the user-specific risk profile validation model comprises building a cluster that represents customary behavior of the user when initiating transactions, and the comparing the validation score against the validation scores of the prior instances comprises determining whether or not the validation score maps to the cluster.
 11. The card of claim 8 wherein the model is configured such that one or more of a principal component analysis (PCA), a Z-score analysis, and/or other outlier detection methods are utilized to compare the validation score against the validation scores of the prior instances of the authorized card users' behavior.
 12. The card of claim 1 wherein each of the validation scores is based on only a final 30 seconds of the card sensor data prior to completion of each respective one of the transactions.
 13. The card of claim 1 wherein the card is configured such that only the validation scores of 1,000 or 500 most recent authorized transactions of the prior instances are stored in the data storage.
 14. The card of claim 2 wherein the action or activity of the user that activates the card comprises one or more of: removing the card from a wallet in which the card is stored, activating a switch or touch-sensitive area of the card, moving the card in proximity to a mobile device known to the card, moving the card in proximity to a near field communication (NFC) device, an action or activity that supplies power to the card, an action or activity that induces electrical activity in the card, and/or activating one of the one or more sensors.
 15. The card of claim 1 wherein, if the transaction is not completed or not authorized, the validation score for the current transaction is discarded.
 16. The card of claim 1 wherein the user-specific risk profile validation model is encrypted for secure storage on the card.
 17. The card of claim 1 wherein the risk score is encrypted for secure storage on the card and/or for secure transmission.
 18. The card of claim 17 wherein an encryption key utilized to decrypt the encrypted risk score is stored on the card.
 19.
